Hi,

It looks like calling the javscript functions:
Code: JavaScript 
window.resizeTo(newWidth,newHeight
or
Code: JavaScript 
window.resizeBy(incWidth,incHeight)
has no effect from a EO Browser.

I am not surprised considering we control the size of the window.

Just that I do not see obvious handlers that we could use to intercept the fact the page invoked either one of these functions, and then we would handling it from there.

Could you please advise on this matter what would be the best approach to handle those calls?

Would you for instance recommend to overwrite them from our wrapper? Or is there events we could hook up to handle them?

Thank you for your input on this matter.

Hi,

This is one of the cases that highlight the difference between a standalone application and an embedder. It probably is not a good idea for us to define any default behavior for such calls. So you may want to implement them yourself however way you want ---- you can simply inject something like this (through WebView.JSInitCode):

Code: C# 
window.resizeTo = function(width, height)
{
    //Put your own implementation here or use JavaScript extension feature to call into the .NET code
}


If you do call into .NET code, make sure your .NET code does not resize the WebView synchronously. Use something like BeginInvoke to do it asynchronously.

Thanks

Thank you, and yes I fully understand why there is no default behavior.
